After giving up gin, horrible indigestion issues (8)
I believe the answer is:
editions
'issues' is the definition.
(edition is a kind of issue)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for editions that I've seen before include "Copies of book about sedition" , "Repros" , "written publications?" , "issues for the press" , "Book published at different times" .)
